461-1. For safe use
GS450h_OM_OM30F70U_(U)
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set
threshold level (the level of force corresponding to an approximately 12 - 18 mph
[20 - 30 km/h] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher in the following situa-
tions:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the front of the vehicle “underrides”, or goes under, the bed of a truck
●Depending on the type of collision, it is po ssible that only the seat belt pretension-
ers will activate.
●The SRS front airbags for the front passenger will not activate if there is no passen-
ger sitting in the front passenger seat. Ho wever, the SRS front airbags for the front
passenger may deploy if luggage is put in the seat, even if the seat is unoccupied.
(  P. 4 9 )
■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags will deploy in the event of an impact that
exceeds the set threshold level (the level of force corresponding to the impact
force produced by an approximately 3300 lb. [1500 kg] vehicle colliding with the
vehicle cabin from a direction perpendicular to the vehicle orientation at an
approximate speed of 12 - 18 mph [20 - 30 km/h]).
●The SRS side and curtain shield airbags may also deploy in the event of a severe
frontal collision.
■Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags, SRS side and curtain shield airbags may also deploy if a seri-
ous impact occurs to the underside of your vehicle. Some examples are shown in the
illustration.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling

■If a warning light comes on, a warning message is displayed, or the 12-volt battery is
disconnected
The hybrid system may not start. In that case, try to start the system again. If the
“READY” indicator does not come on, contact your Lexus dealer.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel
the vehicle with at least enough gasoline to make the low fuel level warning light
(  P. 506, 528) go off. If there is only a small amount of fuel, the hybrid system may
not be able to start. (The minimum amount of fuel to add to make the low fuel level
warning light go out is about 2.6 gal. [10.0 L, 2.2 Imp.gal.], when the vehicle is on a
level surface. This value may vary when the vehicle is on a slope.)
■Electromagnetic waves
●High voltage parts and cables on the hybr id vehicles incorporate electromagnetic
shielding, and therefore emit approximately the same amount of electromagnetic
waves as conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference in some third party-produced radio
parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of the
hybrid battery (traction battery) can change in accordance with driving style and
driving conditions.

■Certifications for the immobilizer system
For vehicles sold in the U.S.A.
FCC ID: NI4TMIMB-3
This device complies with part 15 of the FCC Rules. Operation is subject to the fol-
lowing two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesire d operation.
For vehicles sold in Canada
This device complies with Industry Cana da licence-exempt RSS standard(s). Oper-
ation is subject to the following two conditio ns: (1) this device may not cause interfer-
ence, and (2) this device must accept any interference, including interference that
may cause undesired operation of the device.
CAUTION
■Certifications for the immobilizer system
Changes or modifications no t expressly approved by the party responsible for

CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, caus-
ing rapid and excessive engine braking and possibly an accident resulting in death
or injury.
■Cautions during setting up the display
As the hybrid system needs to be operating during setting up the display, ensure
that the vehicle is parked in a place with adequate ventilation. In a closed area such
as a garage, exhaust gases including harmful carbon monoxide (CO) may collect
and enter the vehicle. This may lead to death or a serious health hazard.
NOTICE
■During setting up the display
To prevent 12-volt battery discharge, ensu re that the hybrid system is operating
while setting up the display features.

■Head-up display
●The head-up display may seem dark and hard to see when viewed through sun-
glasses, especially polarized sunglasses.
Adjust the brightness of the head-up display or remove your sunglasses.
●When the head-up display is turned off, it will remain off even if the power switch is
turned to ON mode after the power switch has been turned off.
●The startup image will be displayed on the head-up display after the power switch
has been turned to ON mode while the head-up display switch is set to on.
■When the 12-volt battery is disconnected
The customize settings of the head-up display will be reset.
CAUTION
■Before using the head-up display
Check that the position and brightness of the head-up display image does not
interfere with safe driving. Incorrect adjustment of the image’s position or bright-
ness may obstruct the driver’s view and lead to an accident, resulting in death or
serious injury.
NOTICE
■To prevent damage to components
●Do not place any drinks near the head-up
display projector. If the projector gets wet,
electrical malfunctions may result.
●Do not place anything on or put stickers
onto the head-up display projector.
Doing so could interrupt head-up display
indications.
●Do not touch the inside of the head-up dis-
play projector or thrust sharp edges or the
like into the projector.
Doing so could cause mechanical malfunc-
tions.
